To all whom 'it may concern.'

Be it known that I, ALBERT C. DALE,- a citizen of the lUnited States, residing at 'Longbeacln in the county of Los Angeles and State of California, have invented a newl and useful Oil-Gas `Generator and Burner, of which the following is a specification.

This invention relates to an apparatus yfor generating gas from hydrocarbon oils,

Another object of the present invention is to produce a device of the character described so that a portion of oil is trapped in the generator', thereby preventing overheatingl of the generator.

Another object of the present invention is to produce a device of the character described in which the burner chamber may be extended to produce a greater vflame surface.

Another object of the present invention is to produce a device of the character described of simple and economical const-ruction having great efficiency for the purposes for which the device is designed.

Other objects and advantages will appear .hereinafter from the following specification.

Referring tothe drawings, which are for illustrative purposes only: Figure 1 kis a longitudinal sectional view through a device embodying a form of my! invention showing the manner of mounting' the same in a fire box of a stove, a portion of the stove being indicated in dotted lines. Fig. 2 is a plan view of the device shown in Fig. 1. F1g.-3 is a transverse sectional view on line :v8-ais Fig. 1.

The device comprises a tubular burner chamber, a mixing chamber Within the burner chamber, and a generator directly above the burner chamber having a connec tion to deliver .gas into the mouth ofthe mixing chamber.

The burner chamber consists of an inner tubular member 1 telescoped within an outer tubular member ,2. A11 arch or division wall 3 extends from the front wall 4 of the burner chamber 1 to the rear end of the chamber 1 forming a mixing chamber 5 wit-hin the burner chamber, the rear end ofthe mixing chamber 5 being closed by means of a wall 6. The arch 3 is provided with a series of perforations 7 which deliver the contents of the mixing chamber evenly throughout the length of the inner member 1 of the burner chamber.

The inner member 1 and outer'member 2 are each provided'with a row of transverse slots 8 and 9 respectively which extend across the top of the respective members 1 and l2.l The inner member 1 and outer member 2 are also each provided at each side .of said members with a row of transverse slots 10 and 11 respectively. The

slots 8 and 9 of the members 1 and 2 respectively and the slots 10 and 11 of the members 1 and 2 respectively are arranged so that they register forming outlet open ings or burner slots through which the mixture passes'from the burner chamber to the exterior thereof where the mixture may be burned. To insure the registration of the slots in the. members l and 2 the underside of the member 1 is provided with a series of indentations 12 which are adapted to receive a stop l'mounted on a flat spring 14 secured to the underside of the member by means of rivets 15 or other suitable fastening means The burner portion of the device, as above described, is shown in Fig. 1 asmounted in a fire box 16 ,of a common cook stove, the member 1 being provided with arms or extensions 17 which extend :torvvardly'therefrom and are secured at their forward end by means of bolts 18 to a plate 19 which may be secured in any suitable manner to the front of the stove over a door opening `20 therein.

When the burner is used in a short fire box, or when .it is desirable to direct all of the heat under a single stove lid, as indicated in dotted lines at 22 in Fig. 1, the

outer member 2 is moved forward on the member 1, telescoping the member, in which case the burner surface extends a length equal to the length of the outer member 2,

the member 1 being telescoped within the member 2. When it is desirable to lengthen the burner surface, the member 2 is moved into the position indicated or to any desired position as long as the melnberl 2 is 'not moved out of engagement with the member 1 and the slots in the members 1 and 2 placed in registration as above described.

, oil is delivered into the pan 35 where thelVhen the member 2 is placed in extended position it is understood that the burnerr chamber is lengthened, the mixture passing through the open outer end of the member 1 to the interior of the member 2.

Projecting upwardly from the member 1 is a standard 24 which forms a support for the generator hereinafter described. The upper portion of the member 2 is provided with a slot 25 through which the standard 24 projects and serves to prevent rotation of the member 2 on the member 1, thereby insuring lateral registration of the slots in the respective members 1 and 2.

The generator consists of a pipe or tube 26 supported at its rear end by means of the standard 24, the end of the pipe 26 being closed by means of a cap 26. The forward end of the tube 26 projects through the plate 19 to the exterior of the stove, at lwhich point the tube 26 is provided with a needle valve 27 which regulates the flow of oil from supply pipe 28 through T 29 into the pipe 26. The pipe 26 is also provided with a T 30 for the purpose of receiving a gas delivery pipe 31 which opens at its lower end into needle valve 32, the orifice 33 of Iwhich isA directly `in front of the mixing chamber 5, the valve 32 being regulated by suit-able handle means. 34. It is desirable that all of the oil fed into the generating tube 26 should not be gasied, which would result in overheating the tube 26, and to prevent this the pipe 31 extends upwardlyinto the T 30 ,to about the center line of the tube 26, thereby forming a trap which in sures that the lower portion of the generating tube 26 would be covered with oil.

A drip pan 35 is provided, which may be set on the grate of the stove, the pan 35 being of suflicient size to extend a short distance under the burner for the purpose of catching any oil which might drop from the mixing chamber, the mixing chamber being provided with a lip 36 which prevents oil from ruiming back on the underside of the chamber.

The'device operates as follows: Oil is admtted froni a suitable reservoir placed so that the oil from the same will be delivered by gravity through the pipe 2S and valve 27 into the generating tube 26. The valves 27 and 32 are opened until a small quantity of same is lighted, and the heat generated thereby7 gasifies a portion of the oil in the tube 26. When the oil in the pan 35 has been burned, the' valve 32 is opened and the gas in the tube 26 passes through pipe 31, valve 32 into the open end of the mixing chamber 5, at the same time drawing in a supply of heated air from the tire box of the vheat from the whole burner surface.
